Noisy diff diff is noisy, gets louder when i turn right, when i turn left the noise goes away, diff noise is getting worse

if hub bearing replacement did not fix the noise

when noises are on left and right turns
that has CV joints /drive shafts
would say they are the issue
replace both sides

and replace the left hand hub bearing at the same time

could be a front wheel bearing. as your driving turn wheel left and then right and see if the noise gets worse , usually the noise will get worse on the oppisite wheel of which you are turning eg: turn left and you the noise louder it should be right wheel bearing. Check tires first to see if there is any choppieness to them, this also can create a noise

the noise should change or go away when you turn the wheel to the right or left. if it does it sounds like you have a bad wheel bearing. Typically if you turn to the left and it gets louder its the right side if you turn to the right and it gets louder its the left side. Or if you turn to the right and it goes away its the right side and if it goes away when turning to the left it is the left side.

Another thing you can do is safely jack up the front of the vehicle. With the transmission in neutral rotate each wheel by hand while holding onto the strut spring with your other hand. You should be able to feel the noise you hear in the strut spring if it is the bearing.

Suspect a worn left side spider gear or it's bearing in the differential. If a limited-slip differential, the left side clutch may be grabbing somewhat. In any case, the differential will need to be removed from the case to service any worn or defective components. Rear end service is not for inexperienced mechanics. Have you checked the fluid level in the differential? Hope this helps!

Hi,

Its a good possibilty,The Bearing will humm ,if no grease in them or very little. I would Stop driving it to save some money cause if its a wheel bearing, it will only get worse and its 1st of all not SAFE,2nd The bearing will also damage your Hub and Spindle,and any other front end parts that heat from the bearing will Damage,Like your Front Brake Rotor and Brake Pads. So .Pull off that wheel and Check it out,You'll have to Pull Caliper and Rotors as Well.

Many times if one side goes out (Wheel Bearing) normally not long before both==I recommend you Change out Wheel Bearings and Bearing Races On BOTH sides.

Possibly. Could also be wheel bearing, brake pad, or other component. Isolate the noise, if you can, by driving slowly and turning left and right, seeing if the noise changes in either direction. A noise that gets louder indicated a problem with the OPPOSITE side or outside components on the turn, as they have to turn slightly faster.

CV joints usually make horribly loud grinding sounds. See if the sound is worse when 4WD is engaged or goes away. It is also possible that the auto-locking hub could be a problem. The hubs were a large problem in the early days of the product.

Replace the right front wheel bearing

Hello! If the humming noise is speed related(gets louder as vehicle speed increases)check front wheel bearings. If the noise goes away when turning one way or the other then it will most likely be in the front wheel bearing. If you turn the wheel(while moving)to the right and the noise goes away it is on the right side. If you turn the wheel to the left and the noise goes away its on the left side. Hope this information helps!

it sounds like a bad main and thrust bearing

If it's wheel bearings, they should get louder the faster you go. Also, if you have one going out, loading up the suspension on that side will make it louder. For instance, if you have a bad front left bearing, and you take a right-hand turn at speed on the highway, that will load the left side suspension since the car will roll to the left. The noise would get louder. Similarly, if you took a left turn, and the weight shifted off of the left side, the noise would go away.

Try jacking up the car and grabbing the wheel at the top and bottom and shaking it hard. If you get any play or looseness in the wheel, chances are the bearing is bad.
